Chapter4 Voice over IP Configurations
H.323v2 Dynamic Mapping Configuration
Note For additional information on the gateway configuration commands, see the document Configuring
H.323 VoIP Gateway for CiscoAccess Platforms, available on CCO and the Document CD-ROM.
Step11 Repeat for each possible outgoing destination:
uBR924(config)# dial-peer voice id-number voip
Specify a unique id-number for this outgoing
dial-peer and enter dial-peer configuration mode.
Step12 uBR924(config-dial-peer)# destination-pattern digits Specify the telephone number(s) associated with this
dial-peer.
Step13 uBR924(config-dial-peer)# session target ras Specify that RAS will be used to resolve the
destination for the dial-peer.
Step14 uBR924(config-dial-peer)# dtmf-relay [cisco-rtp]
[h245-signal] [h245-alphanumeric]
Optionally configure the dial peer to support out of
band signaling of DTMF tones.
Step15 uBR924(config-dial-peer)# exit Exit dial-peer configuration mode.
Step16 uBR924(config)# gateway Enable the VoIP gateway on the
Cisco uBR924 router.
Step17 uBR924(config)# interface cable-modem 0 Enter interface configuration mode for the cable
interface.
Step18 uBR924(config-if)# (enter appropriate cable interface
configuration commands)
Enter whatever commands are needed to configure
the cable interface such as IP address, downstream
channel, whether DOCSIS-bridging is enabled, and
so forth.
Step19 uBR924(config-if)# h323-gateway voip interface Specify that the cable interface is the H.323
Gateway VoIP interface.
Step20 uBR924(config-if)# h323-gateway voip id gatekeeper-id
ipaddr IP-address port-number
Identify the RAS gatekeeper by specifying its
gatekeeper ID (which must match the ID configured
on the gatekeeper), its IP address, and the port
number which services gateway requests.
Step21 uBR924(config-if)# h323-gateway voip h323-id
interface-id
Specify the H.323 ID for this interface. This ID is
any string that uniquely identifies this gateway to the
gatekeeper. Typically, this is the gateway’s name and
domain (such as “ubr924@cisco.com”).
Step22 uBR924(config-if)# h323-gateway voip tech-prefix prefix (Optional) Specify a technology prefix to identify
the type of service this gateway can provide. If more
than one service is being provided, give this
command for each separate technology prefix. (The
prefix is defined at the gatekeeper and can up to 11
characters long, with the pound sign (#) as the last
character.)
Step23 uBR924(config-if)# exit Exit interface configuration mode.
Step24 uBR924# copy running-config startup-config
Building configuration...
Save the configuration to nonvolatile memory so
that it will not be lost in the event of a reset, power
cycle, or power outage.
Step25 uBR924# show startup-config Display the configuration file that was just created.
